FITC can inhibit the antimonite-stimulated ATPase activity of ArsA and a combination of ATP and antimonite can completely protect ArsA from the inactivation of FITC. The Lys residue in the glycine-rich loop in ArsA is possibly one of the sites for FITC modification. Antimonite can induce the fluorescence resonance energy transfer between FITC and TRITC that separately labeled on different ArsA molecules.

研究还发现FITC对ArsA的ATP酶活性有抑制作用，ATP和SbO〓与ArsA的结合完全拮抗这种抑制，说明ATP和SbO〓与ArsA的结合能够引起ArsA产生一种完全不同于它们单独与其结合时的构象变化，从而使ArsA上FITC的修饰位点变得不易接近，同时ATP结合位点内的Lys可能是FITC在ArsA上的结合位点之一。
